Forming one of a pair of single-storey cottages, built for workers on the Newborough Estate in the 1840s, Ty Crwn was originally of one-room plan. They are built from snecked rubblestone and have a pyramidal slate roof. Both cottages have twentieth century flat-roofed and lean-to additions but the entrances remain in their original openings.
